Question - recently discovered a small leak on our rental property’s roof. The leak is below the gutter well where there has been ponding. It has a low pitched, commercial style roof. Currently has a torch down style with a white coating of flat roof type paint / sealant (unknown what product was used)…..we’d like to put a roll on style sealer over the existing sealant to buy us a few more years. What’s the best product to use? I’d also like to use an epoxy or something to reduce the ponding areas. Any recs on mitigating the ponding? 3rd question - any other words of wisdom for someone whose never done a job like this?
